Fuel Cutoff System

The fuel cutoff system will stop fuel injection during deceleration to prevent excess fuel build-up during periods when oxygen is insufficient for combustion (i.e., closed throttle, high RPM). Fuel cutoff system will also deactivate injectors when engine speed exceeds 6800 RPM. This is done to prevent engine damage due to excessive engine speed. As engine speed drops to less than 6500 RPM, injection will resume.
